推荐答案
如果 virtualenv 是安装在服务器上，您可以创建一个虚拟环境:
If virtualenv is installed on the server, you can create a virtual environment:
virtualenv your_env_name
然后将其激活:
source your_env_name/bin/activate
然后通过
pip install packagename
但是，如果尚未安装virtualenv，则应查看，已经回答了相同的问题.
However, if virtualenv is not installed yet, you should take a look at this thread where the same question has been answered already.
为每个项目使用单独的virtualenv还是更好，因为这样您就可以轻松地使用以下内容导出依赖项
It is still better to use a separate virtualenv for each of your projects, because then you can easily export your dependencies using
pip freeze > requirements.txt
您可以将此Requirement.txt添加到版本控制中，然后，如果您想在另一台计算机上安装项目，则可以一次安装所有依赖项而不会弄乱版本号等:
You could add this requirements.txt to your version control, and later, if you want to install your project on another machine, you can install all dependencies at once without messing with version numbers etc:
pip install -r requirements.txt
